Great in your pocket identifier

Always wanted to be able to identify accurately the beautiful trees that I come across. This hits the nail on the head. Easy train use, gives you percentage hit rate based on the questions you answer. The. You can look at pictures to compare. You can even mark the trees you have found on the map. Definitely a must have. Works on iPad well but great to have on the iPhone so that you always have it.

Tree ID

I love this ap - we've recently moved to the wilds of Norfolk from the wilds of Essex (yup! A superhuman effort to travel so far!).

Seriously though, since arriving here I've found myself being more interest in the trees surrounding us. Equally, having the Bird ID App (from the same studio I believe), I find myself taking a greater interest in the birds in the area.... Having these two apps I seemed to want to know what that tree or bird I've discovered on my travels - can't get this sort of encouragement (in such a passive way) from many other Apps.

No, I'm not going start wearing tweed nor a deer-stalker upon my head 😄😄😎

If you really want to enjoy the countryside...

You can't truly appreciate the diversity of the rural landscape without having some understanding of the trees that populate it -- and what better way to gain that understanding than with the delightful pictures and potted summaries to be found in this application? You can even enjoy the scenery from the comfort of an armchair. What's not to like?
